BACKGROUND: Rotational alignment of the tibial component is important for long-term success of total knee arthroplasty (TKA). This study aimed to compare five axes in normal and osteoarthritic (OA) knees to determine a reliable landmark for tibial rotational alignment in TKA. METHODS: One hundred twenty patients with OA knees and 40 with normal knees were included. The angle between a line perpendicular to the surgical transepicondylar axis and each of five axes were measured on preoperative computed tomography...

Adhesion of the flexor hallucis longus (FHL) muscle to the distal tibia can occur after distal tibial fracture, distal fibular fracture, low tibial osteotomy, soft-tissue injury at the posterior ankle, subclinical compartment syndrome of the distal deep posterior compartment of the leg, or Volkmann contracture after deep posterior compartment syndrome of the leg. The purpose of this Technical Note is to report the endoscopic approach of FHL muscle adhesiolysis. It is indicated in patients with symptomatic adhesion of the FHL muscle and contraindicated if there is entrapment of the FHL muscle or tendon in the fracture callus or if there is extensive fibrosis and contracture of the FHL muscle as a result of Volkmann contracture after deep posterior compartment syndrome of the leg...

Isolated posterolateral corner injury is an uncommon injury that could be a source of unexplained knee pain and dysfunction. Most of these patients present instability caused by concomitant ligament injuries. Numerous studies have shown open approach posterolateral repair or reconstruction surgeries to restore posterolateral rotational stability. Still, there is a certain population of patients who present posterolateral rotation instability without significant injury to the fibular collateral ligament, popliteal fibular ligament, and popliteus tendon...

REVIEW
Lawrence A DiDomenico, Danielle N Butto
Subtalar joint arthrodesis is a procedure used in posttraumatic arthritis, osteoarthritis, tarsal coalition management, posterior tibial tendon dysfunction, and inflammatory arthropathies, and can be used in deformity correction. The goals of the procedure are to eliminate pain, improve function, restore stability, and realign the hind foot. The procedure has high patient satisfaction with low complications while preserving motion in adjacent tarsal joints. Joint preparation is important and time should be spent preparing the joint for successful arthrodesis and the fixation construct needs to be done well and effectively to provide a solid Arbeitsgemeinschaft für Osteosynthesefragen (AO) construct for good results...

Dislocation of the posterior tibial tendon is an uncommon condition. Although surgery is usually performed in most cases of posterior tibial tendon dislocation, postoperative repeat dislocation of the posterior tibial tendon has not been reported in the published data. We report the case of a 27-year-old male patient who experienced repeat dislocation of the posterior tibial tendon after a gymnastic landing, 44 months after initial retinaculum repair. For revision surgery, we reconstructed the flexor retinaculum in conjunction with deepening of the retromalleolar groove, because the groove was hypoplastic...

Tendoscopy is an apparently safe and reliable procedure to manage some foot and ankle disorders.The most common foot and ankle tendoscopies are: Achilles; peroneal; and posterior tibial tendon.Tendoscopy may be used as an adjacent procedure to other techniques.Caution is recommended to avoid neurovascular injuries.Predominantly level IV and V studies are found in the literature, with no level I studies still available.There are many promising and evolving endoscopic techniques for tendinopathies around the foot and ankle, but studies of higher levels of evidence are needed to strongly recommend these procedures...

A technique for posterior cruciate ligament reconstruction is presented. Autologous hamstring tendons are selected as a graft. An interference screw is used for femoral fixation. A suspension device is used for tibial fixation to bring the fixation closer to the articular end of the tibial tunnel. Single diameter tunnels of the same diameter as the graft are created in an outside-in direction.

An accessory navicular bone (AN) is the most common accessory ossicle in the foot. The presence of an AN bone can trigger various foot problems, such as posterior tibial tendon pathology, flattening of the medial longitudinal arch, and medial foot pain. Despite the clinical influence of presence of an AN in foot disease, the research regarding its inheritance is still insufficient. A total of 135 pairs of monozygotic (MZ) twins, 25 pairs of dizygotic (DZ) twins, and 676 singletons from families were enrolled in order to estimate genetic influences on AN...

INTRODUCTION: Patella-post impingement (PPI), contact of the patellar component with the tibial post, occurs during deep knee flexion after posterior stabilized total knee arthroplasty (TKA). PPI can cause anterior knee pain, increased patellar pressure, wear of the polyethylene patellar component and tibial post, and poor range of motion. There have been no reports on the relationship between PPI and tibial post design. The aim of this study was to compare different tibial post designs with regard to PPI incidence...

BACKGROUND: When using the gap-balancing technique for TKA, excessive medial release and varus proximal tibial resection can be associated with internal rotation of the femoral component. Previous studies have evaluated the causes of femoral component rotational alignment with a separate factor analysis using unadjusted statistical methods, which might result in treatment effects being attributed to confounding variables. QUESTIONS/PURPOSES: (1) What pre- and intraoperative factors are associated with internal rotation of the femoral component in TKA using the gap balancing technique? (2) To what degree does femoral component rotation as defined by the navigation system differ from rotation as measured by postoperative CT? METHODS: Three hundred seventy-seven knees that underwent computer-assisted primary TKA attributable to degenerative osteoarthritis with varus or mild valgus alignment in which medial soft tissue release was performed, and those with preoperative radiographs including preoperative CT between October 2007 and June 2014 were included in the study...

PURPOSE: The aim of this study was to investigate the results of total knee arthroplasty (TKA) performed after varus distal femoral osteotomy (VrDFO), in comparison to a control group of TKAs performed as the primary intervention for arthrosis. Main hypothesis was that the medium term results for the two groups would be similar. METHODS: All TKAs performed after VrDFO were extracted from a single centre, prospective database of 4046 arthroplasties. A case-control study was performed with a control group comprising two TKAs performed as the primary intervention for each TKA after VrDFO, and matched for sex, age at intervention, body mass index, the type of arthrosis and the type of implant...

INTRODUCTION: Koutsogiannis' osteotomy has been widely described to treat adult-acquired flatfoot. However, few articles describe its midterm follow-up. Our aim was to study clinical and radiological outcomes at least one year after surgery and to analyze whether a combined procedure on the medial soft tissue affected these outcomes. METHODS: We performed a retrospective study of 30 feet of patients who underwent a Koutsogiannis' osteotomy due to adult-acquired flatfoot stage II and "early stage III": a stage III acquired flatfoot without any important structural deformities...

PURPOSE: Few studies have used MRI to identify the ALL. As it was shown that it is not possible to precisely characterize this ligament in all examination, it is important to identify concomitant lesions that can help in diagnosing ALL abnormalities. It is important to characterise this injury due to its association with anterolateral knee instability. Thus, the present study was performed to determine the frequency of ALL injuries in patients with acute ACL rupture and to analyse its associated knee lesions...

OBJECTIVE: The purpose of this study was to determine the variability of distances between four distinct anatomic landmarks used for the evaluation of patellofemoral alignment while implementing controlled changes in patient positioning during MRI. MATERIALS AND METHODS: Limited MRI was performed of 12 knees in healthy volunteers (10 men, two women; mean age, 28 years) with the knees in four different positions. The four landmarks used were TT (the most anterior point of the osseous tibial tubercle), TG (the nadir of the cartilaginous trochlear groove), PT (the center of the patellar tendon insertion on the tibia), and PCL (the medial border of the posterior cruciate ligament at its insertion along the posterior tibia)...
